Keep the last AutoSaved versions of files for the next session

This policy setting determines whether Excel keeps the last AutoSaved version of a file if a user closes a file without saving it. (Note: AutoSave applies only when AutoRecover is enabled.)

If you enable or do not configure this policy setting, Excel keeps the last AutoSaved version of the file and makes it available to the user the next time the file is opened if the user closes a file without saving it.

If you disable this policy setting, Excel does not keep the last AutoSaved version of the file if the user closes a file without saving it.
